        <h2>Description</h2>
        <p>
      A FLTK widget opcode that creates a button that will close the panel
      window it is a part of.
    </p>
      </div>
      <div class="refsect1">

        <h2>Syntax</h2>
        <pre class="synopsis">ihandle <span class="command"><strong>FLcloseButton</strong></span> "label", iwidth, iheight, ix, iy</pre>
      </div>
      <div class="refsect1">
        <a id="idp103971488"></a>
        <h2>Initialization</h2>
        <p>
      <span class="emphasis"><em>ihandle</em></span> -- a handle value (an integer number) that unequivocally references a corresponding widget. This is used by other opcodes that modify a widget's properties (see <a class="link" href="ControlFltkAppearance.html" title="Modifying FLTK Widget Appearance"><em class="citetitle">Modifying FLTK Widget Appearance</em></a>). It is automatically output by <span class="emphasis"><em>FLcloseButton</em></span> and must not be set by the user label. (The user label is a double-quoted string containing some user-provided text placed near the widget.)
    </p>
        <p>
      <span class="emphasis"><em><span class="quote">“<span class="quote">label</span>”</span></em></span> -- a double-quoted string containing some user-provided text, placed near the corresponding widget.
    </p>
        <p>
      Notice that with <span class="emphasis"><em>FLcloseButton</em></span>, it is not necessary to call the <a class="link" href="FLsetTextType.html" title="FLsetTextType"><em class="citetitle">FLsetTextType</em></a> opcode at all in order to use a symbol. In this case, it is sufficient to set a label starting with <span class="quote">“<span class="quote">@</span>”</span> followed by the proper formatting string.
    </p>
        <p>
      The following symbols are supported:

      </p>
        <div class="mediaobject">
          <img src="images/symbols.png" alt="FLTK label supported symbols." />
          <div class="caption">
            <p>FLTK label supported symbols.</p>
          </div>
        </div>
        <p>
    </p>
        <p>
      The @ sign may be followed by the following optional <span class="quote">“<span class="quote">formatting</span>”</span> characters, in this order:

      </p>
        <div class="orderedlist">
          <ol class="orderedlist" type="1">
            <li class="listitem">
              <p><span class="quote">“<span class="quote">#</span>”</span> forces square scaling rather than distortion to the widget's shape.</p>
            </li>
            <li class="listitem">
              <p>+[1-9] or -[1-9] tweaks the scaling a little bigger or smaller.</p>
            </li>
            <li class="listitem">
              <p>[1-9] rotates by a multiple of 45 degrees. <span class="quote">“<span class="quote">6</span>”</span> does nothing, the others point in the direction of that key on a numeric keypad.</p>
            </li>
          </ol>
        </div>
        <p>
    </p>
        <p>
      <span class="emphasis"><em>iwidth</em></span> -- width of widget.
    </p>
        <p>
      <span class="emphasis"><em>iheight</em></span> -- height of widget.
    </p>
        <p>
      <span class="emphasis"><em>ix</em></span> -- horizontal position of upper left corner of the valuator, relative to the upper left corner of corresponding window (expressed in pixels).
    </p>
        <p>
      <span class="emphasis"><em>iy</em></span> -- vertical position of upper left corner of the valuator, relative to the upper left corner of corresponding window (expressed in pixels).
